The term “coupled” is defined as connected, although not necessarily directly, and not necessarily mechanically; two items that are “coupled” may be unitary with each other. The terms “a” and “an” are defined as one or more unless this disclosure explicitly requires otherwise. The term “substantially” is defined as largely but not necessarily wholly what is specified (and includes what is specified; e.g., substantially 90 degrees includes 90 degrees and substantially parallel includes parallel), as understood by a person of ordinary skill in the art. In any disclosed embodiment, the terms “substantially,” “approximately,” and “about” may be substituted with “within [a percentage] of” what is specified, where the percentage includes 0.1, 1, 5, and 10 percent.

Further, a device or system that is configured in a certain way is configured in at least that way, but it can also be configured in other ways than those specifically described.

The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “including”), and “contain” (and any form of contain, such as “contains” and “containing”) are open-ended linking verbs. As a result, an apparatus that “comprises,” “has,” “includes,” or “contains” one or more elements possesses those one or more elements, but is not limited to possessing only those elements. Likewise, a method that “comprises,” “has,” “includes,” or “contains” one or more steps possesses those one or more steps, but is not limited to possessing only those one or more steps.

Any embodiment of any of the apparatuses, systems, and methods can consist of or consist essentially of—rather than comprise/include/contain/have—any of the described steps, elements, and/or features. Thus, in any of the claims, the term “consisting of” or “consisting essentially of” can be substituted for any of the open-ended linking verbs recited above, in order to change the scope of a given claim from what it would otherwise be using the open-ended linking verb.

The feature or features of one embodiment may be applied to other embodiments, even though not described or illustrated, unless expressly prohibited by this disclosure or the nature of the embodiments.

Details associated with the embodiments described above and others are described below.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

Referring now to the drawings, and more particularly to FIGS. 1-9, shown therein and designated by the reference numeral 10 is one embodiment of the present pest-management apparatuses. In the embodiment shown, apparatus 10 comprises a base 14 and a lid 18 configured to be coupled to (e.g., is shown in FIGS. 4-9 coupled to) base 14 such that the base and the lid cooperate to define (e.g., when the lid and base are coupled together in a closed configuration, as is shown in FIG. 4) a chamber 22 having at least one entrance opening 26 sized to permit a rodent to enter apparatus 10 (e.g., chamber 22) through opening 26. In some embodiments, base 14 and lid 18 may cooperate to define a chamber having a plurality of (e.g., more than one) entrance openings. For example, in the embodiment shown, base 14 and lid 18 cooperate to define a chamber 22 having a second entrance opening 28. In the embodiment shown, base 14 and lid 18 cooperate to define a chamber 22 having entrance openings 26 and 28 when base 14 and lid 18 are coupled together in a closed configuration (FIG. 4). In the depicted embodiment, entrance openings 26 and 28 are formed only in base 14. Accordingly, one or both of entrance openings 26 and 28 may each be entirely defined by only one of the lid and the base (e.g., the entire perimeter of the respective opening may be defined by only one of the lid and the base). However, in other embodiments (such as the embodiment shown in FIGS. 11-13), one or both of entrance openings 26 and 28 may each be cooperatively defined by the base and the lid (e.g., when the lid is in a closed configuration relative to the base).

In some embodiments, at least one of base 14 and lid 18 (e.g., base 14, in the embodiment shown in FIGS. 1-10, or lid 18 a, in the embodiment shown in FIGS. 11-13) comprises a sidewall 30 at least partially defining an external perimeter of apparatus 10, and configured to discourage a rodent (e.g., at or near sidewall 30) from climbing onto lid 18. More particularly, in some embodiments, at least one of base 14 and lid 18 (e.g., base 14, in the embodiment shown in FIGS. 1-10, or lid 18 a, in the embodiment shown in FIGS. 11-13) comprises a sidewall 30 at least partially defining an external perimeter of apparatus 10, and configured with at least a curved portion (e.g., first portion 54) to discourage a rodent (e.g., at or near sidewall 30) from climbing onto lid 18. In the embodiment shown, at least portions of sidewall 30 can also be described as being configured to direct a rodent toward a respective entrance opening 26 or 28. In the embodiment shown, sidewall 30 has a height 34, and an upper portion 38 of sidewall 30 is disposed outwardly (e.g., relative to chamber 22) of a lower portion 42 of the sidewall by a distance 46 (see FIG. 5) of at least 20 percent (e.g., 25, 30, 35, 40, 45, or more percent) of height 34. In the embodiment shown, sidewall 30 includes a surface 50 extending from lower portion 42 to upper portion 38. In the embodiment shown, surface 50 includes a curved (e.g., a concave or substantially arcuate) first portion 54, a substantially straight second portion 58, and a curved (e.g., a convex or substantially arcuate) third portion 62. In other embodiments, surface 50 can have any suitable shape (e.g., can be substantially straight between the lower portion and the upper portion, curved (e.g., concave or convex, including substantially arcuate) between the lower portion and the upper portion, and/or the like).

In the embodiment shown, base 14 can be described as having a left side 63, a right side 64, a front 65, and a back 66. In the embodiment shown, the portions of sidewall 30 along left side 63, right side 64, and front 65 all have substantially similar shapes or profiles, as described above and depicted, for example, in FIG. 5. In the embodiment shown, back 66 has a profile or shape that is different than the shape or profile of left side 63, right side 64, and front 65. In the embodiment shown, back 66 is configured so that it may be disposed adjacent to a substantially vertical surface (e.g., a wall) exterior to apparatus 10 such that the space between back 66 and the substantially vertical surface is minimized (e.g., such that a portion, up to and including all, of back 66 is in contact with the surface). In such embodiments, back 66 may be described as vertically-oriented, or, more specifically, oriented vertically relative to floor 94 of base 14. In other embodiments, back 66 may have a shape or profile that is substantially similar to that of sides 63, 64 and/or front 65 (e.g., that is configured to discourage a rodent from climbing onto lid 18, and/or to direct a rodent toward entrance opening 26 and/or entrance opening 28, and/or the like).

In some embodiments, lid 18 has a first end or edge 68 and a second end or edge 70, and one of end 68 and end 70 is coupled (e.g., pivotally, detachably, etc.) to base 14. For example, in the embodiment shown, edge 70 is coupled to base 14 along back 66. In other embodiments, lid 18 may be configured to be coupled to base 14 along any one or more of sides 63, 64 or front 65. In some embodiments, lid 18 may be configured to be coupled to two or more of sides 63 and 64, front 65, and/or back 66 of base. In the embodiment shown, lid 18 is unitary with base 14 (e.g., base 14 and lid 18 comprise a single piece of material in which lid 18 is pivotally coupled to base 14 via living hinge 72). In the embodiment shown, end 68 of lid 14 is configured to be detachably coupled to base 14 by a lip 74 that is configured to extend around and contact a peripheral edge 76 of base 14 (e.g., when lid 18 is in a closed configuration relative to base 14) to resist separation of the lid from the base (e.g., to resist opening of the lid relative to the base). In other embodiments, lid 18 is configured to be removably coupled to base 14 by at least one latch, lock, and/or the like.

In the embodiment shown, lid 18 comprises at least one transparent viewing window 78 (e.g., one, as shown) through which a user can view at least a portion of chamber 22. In some embodiments, viewing window 78 is at least partially detachable (e.g., via a latch) from lid 18. In some embodiments, viewing window 78 may be unitary with lid 18, such as where the material for lid 18 and window 78 are both transparent. In the embodiment shown, lid 18 comprises a substantially planar portion 82 and a reinforcing portion 86. In the embodiment shown, reinforcing portion 86 comprises one or more ribs 90. In some embodiments, reinforcing portion 86 may comprise any number of reinforcing structures (e.g., ribs, rods, a mesh, etc.) and/or materials (e.g., plastic, steel, aluminum, etc.) configured to reinforce lid 18. In the embodiment shown, reinforcing portion 86 is interior to apparatus 10 when lid 18 is coupled to base 14 in a closed configuration (e.g., FIG. 4). In other embodiments, reinforcing portion 86 may be exterior (e.g., extending outwardly from substantially planar portion 82) to apparatus 10 (e.g., relative to chamber 22) when lid 18 is coupled to base 14 in a closed configuration.

In the embodiment shown, lid 18 comprises a latch 76 a configured to resist separation of lid 18 and base 14 when lid 18 is in a closed configuration relative to base 14. For example, in the embodiment shown, latch 76 a is configured to engage a corresponding lip or shelf 77 in base 14. In some embodiments, at least one of base 14 and lid 18 comprises a release opening configured to permit a user to release lid 18 relative to base 14 to permit the apparatus to transition from a closed configuration to an open configuration. For example, in the embodiment shown, base 14 comprises release opening 76 b that permits a user's finger or other object to extend through release opening to depress latch 76 a relative to shelf 77. For example, The at least one of base 14 and lid 18 that comprises the release opening(s) can be configured such that the edge(s) defining the release opening are configured to prevent a user from injury. (e.g., if a user extends a finger through the release opening), such as, for example, via beveled edges, edges comprising a radius, and similarly smoothed edges. For example, in the embodiment shown, the edges of base 14 that define release opening 76 b are rounded or radiused to eliminate or exclude sharp edges that could otherwise injure or irritate the skin of a user that extends a finger through release opening to release latch 76 a.

In some embodiments, base 14 comprises a floor 94 configured to prevent movement (e.g., with non-slip material, screws, etc.) of apparatus 10 relative to a surface (e.g., a substantially horizontal surface) on which apparatus 10 is disposed or supported. For example, in some embodiments, a lower or bottom surface of floor may be textured and/or may include a rubber or adhesive surface. In the embodiment shown, floor 94 is unitary with sidewall 30. In other embodiments, floor 94 may be detachably coupled (e.g., via latches) to sidewall 30, or floor 94 may be omitted.

In some embodiments, apparatus 10 comprises one or more separators (e.g., on separators 96, as shown) configured such that if lid 18 and base 14 are coupled together to define chamber 22 (e.g., in a closed configuration), the one or more separators 96 prevent a rodent from accessing at least a portion of the chamber except by climbing over the one or more separators. For example, in the embodiment shown, the separator(s) divide chamber 22 into a first portion 98 (e.g., a rodent capture portion 98, as shown) and a second portion 100 (e.g., an entry portion 100, as shown) and are configured to prevent a rodent from traversing from the entry portion to the rodent capture portion except by climbing over the one or more separators. In the embodiment shown, rodent capture portion 98 and entry portion 100 are in fluid communication. In the embodiment shown, rodent capture portion 98 of chamber 22 is configured to resist a rodent's exit from apparatus 10. For example, in some embodiments, an adhesive (e.g., an adhesive mat) is disposed in rodent capture portion 98 of chamber 22 (e.g., coupled to floor 94).

In other embodiments, the one or more separators can be disposed nearer and/or at an entrance 26 (e.g., at both entrances 26) such that a rodent is prevented from entering the chamber except by climbing over the one or more separators.

In the embodiment shown, separator 96 extends between vertically-oriented grooves 102 defined in the interior of base 14 such that separator 96 can be removed and/or re-inserted (e.g., for replacement) by sliding separator 96 vertically. In other embodiments, separator 96 can be unitary with base 14, or separator can be unitary with lid 18 (e.g., such that the separator extends downward from the lid, extends into chamber 22 when lid 18 is closed relative to base 14, and is removed from chamber 22 when lid 18 is opened relative to base 14).

As noted, separator 96 is configured to prevent a rodent from traversing from entry portion 100 to rodent capture portion 98 except by climbing over the separator. More particularly, in this embodiment, separator 96 comprises an elongated member having a planar configuration with a lower edge 96 a that is spaced from floor 94 by a distance that is small enough to prevent a rodent from passing under separator. For example, in the embodiment shown, lower edge 96 a of the separator is spaced from floor 94 by a distance of between 0.25 inches and 0.35 inches. In other embodiments, lower edge 96 a of the separator can contact floor 94 (e.g., with discrete openings at or above the lower boundary to permit insects to crawl under or through the separator). In other embodiments, lower edge 96 a can be separated by any distance of less than 0.5 inches (e.g., less than any one of, or between any two of: 0, 0.1, 0.2, 0.3, 0.4, and/or 0.5 inches). In the embodiment shown, an upper edge 96 b of the separator is disposed at a distance of between 1 and 1.25 inches from floor 94. In other embodiments, upper edge 96 b can be disposed at any height or distance from the interior floor of the bait station (e.g., between 0.75 and 1.5 inches for mice, or a greater distance for rats) that requires (while still leaving spaced between separator 96 and lid 18 for) a rodent of expected size to have to climb over separator 96 to traverse from entry portion 100 to rodent capture portion 98. In some embodiments, upper boundary 96 b of the separator is spaced from the lid (when lid 18 is in a closed configuration relative to base 14) by a distance of greater than 0.25 inches (e.g., greater than any one of, or between any two of: 0.25, 0.5, 0.75, and/or 1 inch). For example, in the embodiment shown, when lid 18 is closed relative to base (FIGS. 4-5), upper boundary 96 b is spaced from a bottom surface of the lid by a distance of between 0.8 and 0.9 inches. In other embodiments, the distance between lid 18 and upper boundary 96 b can be any suitable distance that permits a targeted rodent species (e.g., a mouse or rat) to climb over the separator (e.g., is such that it is easier for the rodent to climb over the separator than to crawl under the separator).

In this embodiment, rodent capture portion 98 can be covered with an adhesive and forcing a rodent to climb over separator 96 increases the likelihood of the rodent making sufficient contact with the adhesive to be captured. For example, absent separator 96, a rodent can place a single foot on the adhesive in rodent capture portion 98 and may be able to withdraw the single foot upon realizing that the adhesive is present. In contrast, in the present embodiments, the rodent is forced to commit to entering rodent capture portion 98 by climbing over separator 96, thereby increasing the likelihood that at least two of the rodent's feet will contact the adhesive and the rodent will be captured and prevented from escaping. In the embodiment shown, separator 96 is disposed such that the width (measured in a direction extending from front 65 to back 66) of entry portion 100 is less than a length (measured in a direction extending from side 63 to side 64) of entry portion 100, and may be sized (e.g., with a width that is small enough) to discourage rodents within a certain size range from turning around in entry portion 100 (and thereby from exiting apparatus 10 without entering and/or becoming trapped in rodent capture portion 98).

In some embodiments, separator 96 includes a reflective surface. For example, in the planar configuration of separator 96, the side of separator 96 that faces entry portion 100 can be reflective (e.g., can be covered with a reflective paint, reflective tape).

In some embodiments, separator 96 comprises a translucent material (e.g., a transparent material) to allow a rodent to partially and/or entirely see through at least part of the separator, such as, for example, to resist a rodent's reluctance to climb over the separator.

In some embodiments, at least one of base 14 and lid 18 (e.g., base 14, in the embodiment shown in FIGS. 1-10, or lid 18 a, in the embodiment shown in FIGS. 11-13) comprises at least one protrusion (e.g., two protrusions, three protrusions, or more) extending outwardly relative to chamber 22. For example, in the embodiment shown in FIGS. 1-10, base 14 comprises a plurality of protrusions 106 configured to discourage a rodent from traveling in at least one non-vertical (e.g., horizontal) direction away from entrance opening 26 and/or entrance opening 28. In the embodiment shown, protrusions 106 are unitary with base 14 (e.g., sidewall). In other embodiments, protrusion(s) 106 may be releasably and/or adjustably coupled to at least one of base 14 and lid 18. In the embodiment shown, two protrusions 106 extend from each of sides 63 and 64, with one protrusion at or relatively near front 65 and another protrusion at or relatively near back 66. In other embodiments, protrusion(s) 106 may extend from any suitable portion of base 14 (e.g., any suitable position along sidewall 30, such as, for example, front 65). In the embodiment shown, protrusions 106 extend along substantially the entire height 34 of sidewall 30. In other embodiments, protrusions 106 may extend less than the entire height 34 (e.g., may be vertically shorter than sidewall 30) while still being configured to discourage a rodent from traveling in at least one non-vertical direction away from entrance opening 26 and/or entrance opening 28. In the embodiment shown, protrusions 106 are substantially planar. In other embodiments, protrusion(s) 106 can have any shape (e.g., curved, triangular, etc.) configured to discourage a rodent from traveling in at least one non-vertical direction away from an entrance opening (e.g., 26 or 28). Protrusions 106 may each be disposed at a non-parallel angle (e.g., 90, 75, 60, 45, 30, or less degrees) relative to the portion of sidewall 30 from which the protrusion extends. For example, in the embodiment shown, each protrusion 106 is disposed at an angle of between 60 and 90 degrees relative to the part of sidewall 30 from which it extends, and is substantially perpendicular to floor 94 of the base.

In some embodiments, base 14 and lid 18 cooperate to define a chamber (e.g., 22) having at least one secondary opening 110 (e.g., a plurality of secondary openings 110, as shown) sized differently (e.g., smaller, as shown) than at least one entrance opening (e.g., 26 and/or 28). For example, in the embodiment shown, base 14 defines secondary openings 110. Secondary opening(s) 110 may also be shaped differently than at least one entrance opening (e.g., 26, 28). In other embodiments, the secondary openings can comprise multiple shapes (e.g., square, triangular, circular, etc.). In the embodiment shown, secondary opening 110 are configured to allow pheromones to escape chamber 22 (e.g., to attract pests toward apparatus 10). For example, in the embodiment shown, apparatus 10 is shown with a container (e.g., a tube) 112 configured to hold and release pheromones (and/or scented bait) to attract rodents to apparatus 10. In some embodiments, secondary opening 110 may be configured to allow pests (e.g., cockroaches, scorpions, spiders) smaller than a rodent to enter apparatus 10 (e.g., into chamber 22) while preventing rodents from entering the apparatus through the secondary openings.

In some embodiments, apparatus 10 is configured to prevent liquid below a certain level from entering chamber 22 through the at least one entrance opening (e.g., 26 and 28) and the secondary openings (e.g., 110). For example, in the embodiment shown, the bottom or lowermost portions of each of entrance openings 26 and 28, and of secondary openings 110 are disposed a distance above the bottom of floor 94 (e.g., as defined by a raised edge 114) to resist and/or prevent liquid on a surface on which the apparatus is disposed from entering through the openings.

In the embodiment shown, entry portion 100 of chamber 22 is in fluid communication with entrance opening 26 and with entrance opening 28. In the embodiment shown, entry portion 100 provides an entryway for a rodent entering through one of entrance openings 26, 28 to access rodent capture portion 98. In the embodiment shown, entrance openings 26 and 28 are disposed on substantially opposite sides (e.g., right side 64 and left side 63, respectively) of apparatus 10. In this embodiment, entrance opening 26 and entrance opening 28 are configured such that an axis 124 extends through both of openings 26 and 28 (e.g., such that axis 124 is substantially parallel to floor 94). In other embodiments, axis 124 may extend through the entrance openings at an angle that is not perpendicular (e.g., 75, 60, 45, or less degrees) to the respective planes of openings 26 and 28. In other embodiments, entrance openings 26 and 28 may be disposed at any suitable positions relative to sides 63 and 64, front 65, and/or back 66.

In some embodiments, at least one of base 14 and lid 18 (e.g., base 14, in the embodiment shown in FIGS. 1-10, or lid 18 a, in the embodiment shown in FIGS. 11-13) comprises at least one divider disposed in entry portion 120. For example, in the embodiment shown in FIGS. 1-10, base 14 includes a divider 126 that is configured to prevent a rodent from entering apparatus 10 through one entrance opening (e.g., 26) and exiting apparatus 10 through another entrance opening (e.g., 28) without first passing through rodent capture portion 119. In the embodiment shown, divider 126 is further configured to prevent a rodent outside apparatus 10 from seeing one entrance opening (e.g., 28) through the other entrance opening (e.g., 26). In the embodiment shown, divider 126 is further configured to encourage rodents (e.g., in entry portion 100) to enter rodent capture portion 98. In some embodiments, divider 126 extends inward from and/or is coupled (e.g., releasably, detachably, etc.) to sidewall 30. For example, in the embodiment shown, divider 126 is unitary with sidewall 30. In the embodiment shown, divider 126 is disposed substantially midway between entrance opening 26 and entrance opening 28. In other embodiments, divider 126 may be disposed closer to one entrance opening than another entrance opening. In the embodiment shown, divider 126 has a first end 130 and a second end 134 disposed closer to rodent capture 100 portion than first end 130. In the embodiment shown, first end 130 is wider than second end 134. In the embodiment shown, divider 126 is symmetric about an axis 136 such that divider 126 appears substantially similar whether viewed through entrance opening 26 or entrance opening 28. In the embodiments, second end 134 of divider 126 is a greater distance from the center of entrance opening 26 than at least a portion of first end 130. In some embodiments, first end 130 and second end 134 are substantially the same distance from the center of entrance opening 26. In the embodiment shown, an upper portion of divider 126 includes a recess 138 configured to receive container 112 with and/or directly receive pheromones and/or bait (e.g., scented bait) configured to attract rodents.

FIG. 10 depicts apparatus 10 a having a base 14, a lid 18, and an alternate embodiment of the present separators. In this embodiment, apparatus 10 a comprises two separators: a lower wire 96 c and an upper wire 96 d. Together, wires or separators 96 c and 96 d function similarly to separator 96, with lower wire 96 c positioned similarly to lower edge 96 a of separator 96, and with upper wire 96 d positioned similarly to upper edge 96 b of separator 96.

In the embodiments shown, apparatuses 10 and 10 a (e.g., at least one of and/or both of base 14 and lid 18, respectively) may comprise plastic. For example, in some embodiments, base 14 and/or lid 18 comprise a plastic selected from the group consisting of: polypropylene (PP), polystyrene (PS), high impact polystyrene (HIPS), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate (PC), polyethylene (PE), and polycarbonate/acrylonitrile butadiene styrene (PC/ABS), polycarbonate polybutylene terephthalate (PBT), acrylonitrile styrene acrylate (ASA), polyurethanes, nylon (often referred to as polyamide (PA)), combinations thereof, and/or other plastics or polymers. In at least some embodiments, base 14, lid 18, and/or separator 96 (or separators 96 c and/or 96 d) comprises a scented plastic (e.g., a plastic embedded with a scent that mimics peanut butter, apple, or another scent that is selected to attract rodents. In other embodiments, the present apparatuses (e.g., at least one of and/or both of base 14 and lid 18, respectively) comprise a non-plastic material, such as, for example, a metal (e.g., steel, iron, aluminum, copper, brass, or the like), fiberglass, carbon fiber, synthetic materials, and other suitably durable or rigid materials.
